Bitcoin is currently using the secp256k1 curve. Understand that Ed25519 is technically superior -- i.e., offers better security than ECDSA and DSA, speed and most importantly, I think, resistance against side-channel attacks.

Sia, Scorex, BigchainDB, Chain Core, Monero are some examples where ED25519 is used.

Understand that BIP32 made mention of Ed25519. Has BIP32 and/or ED25516 been implemented in Bitcoin or?
